The Lockheed Hudson was a patrol aircraft that was used by Great Britain and also by the United States as the A-29 during World War II. Developed from the Lockheed Model 14 Super Electra at short notice to provide a Prototype for a visit by the British Air Commission who were in the US looking to procure aircraft.
Developed from a civilian transport, the Hudson was a mid-wing, twin-engined bomber with the distinctive Lockheed twin tail boom. First model Hudsons were powered by the Wright GR-1820-G-102A each of which developed 1100hp, capable of pushing the HUdson to just under 400KPH. Defensive armament were two forward firing 7.62mm machineguns and a similar number in a ventral turret. Offensive armament was up to 635KG of bombs or depth charges.
